Cisco VIM 2.2, provides a complete automation of the cloud deployment. Cisco VIM, of this feature is to automate day-0 configuration of N9xxx series Top of Rack(ToR ) switches. The feature is optional and only applies to Pods that are running without ACI. For ToR switch details related to ACI, refer to the section, "Enabling ACI in Cisco VIM".The purpose is to automate Power-On Auto Provisioning (post-POAP) configuration on ToR offering of Cisco VIM, which constitutes of one or more pair of identical Cisco N9300 series switches. The day-0 ToR automation configures the interfaces connected to the management (br_mgmt), control, compute, and storage nodes of the pod. In addition, it configures the VPC peer link interfaces for ToR pairs. The automation handles both B and C-series pods. The automation includes configuration of the edge ports in the leaf switches off which the hosts hang-out and the VPC peer link between the switches. The Auto-Configuration feature does not include the configuration of the spine switches, and the connectivity between the leaf and the spine; that is the upstream link of the spine switches that carry the external VLAN connectivity.

As the feature is a post-POAP automation provisioning, the management interface, vrf, and admin user needs to be pre-provisioned on each of the ToR switch. Also, ssh needs to be enabled in each ToRs. The recommended N9K switch software versions are 7.0(3)I4(6) and 7.0(3)I6(1). Bootstraping the ToR image is still a manual process. The installer API interface (br_api) on the management node needs to be up and running, and the ssh to the management node through SSH must be working. You should be able to access each of the ToRs through its management interface from the Cisco VIM management node using SSH.

The Cisco VIM configuration file, setup_data.yaml, installs and configures the VIM deployment. When creating this file, take extreme care. Any change to this configuration after deployment, with the exception (example: NFVIMON, of adding and removing nodes etc) will cause a stack redeployment. Pay particular attention to the pod networking layout plan configured in setup_data.yaml because any future changes to it will require the pod to be reinstalled.

If your configurations are correct, the installation will go smoothly. Cisco recommends using a YAML editor on Linux (PyCharm, Komodo or vi/vim with YAML plugin) to edit this file. Items shown in brown must be changed to your specific testbed. Do not copy the examples shown below into your YAML file, because your browser might render the characters differently. If you are using the Cisco VIM installer, you will not be able to update the OpenStack config files (for example, ml2_conf.ini, and other files) directly. All OpenStack configurations must be in the setup_data.yaml file. This ensures that the installer has a view of the OpenStack deployment, so that it can reliably perform later software updates and upgrades. This ensures a consistent and repeatable installation, which is important. Key setup file parts are shown in the following sections.

The following sections provide examples of Cisco VIM OpenStack configurations in the setup_data.yaml file. OpenStack Admin Credentials

ADMIN_USER: <admin>
ADMIN_TENANT_NAME: <admin tenant>

OpenStack HAProxy and Virtual Router Redundancy Protocol Configuration

external_lb_vip_address: An externally routable ip address in API nework
VIRTUAL_ROUTER_ID: vrrp_router_id #eg: 49 (range of 1-255)
internal_lb_vip_address: <Internal IP address on mgmt network>
#internal_lb_vip_ipv6_address: 2001:c5c0:1234:5678:1002::10   <== optional, enable IPv6 for OpenStack admin endpoint

OpenStack DNS Name Configuration

For web and REST interfaces, names are commonly used instead of IP addresses. You can set the optional external_lb_vip_fqdn parameter to assign a name that resolves to the external_lb_vip_address. You must configure the services to ensure the name and address match. Resolution can be made through DNS and the Linux /etc/hosts files, or through other options supported on your hosts. The Cisco VIM installer adds an entry to /etc/hosts on the management and other Cisco NFVI nodes to ensure that this resolution can be made from within the pod. You must ensure the resolution can be made from any desired host outside the pod.

external_lb_vip_fqdn: host or DNS name matching external_lb_vip_address
#external_lb_vip_fqdn: <host or DNS name matching external_lb_vip_address>
#external_lb_vip_ipv6_address: 2001:c5c0:1234:5678:1003::10   <== optional, enable IPv6 for OpenStack public endpoint
VIRTUAL_ROUTER_ID: <vrrp router id, eg:49>

OpenStack TLS and HTTPS Configuration

Enabling TLS is important to ensure the Cisco VIM network is secure. TLS encrypts and authenticates communication to the cloud endpoints. When TLS is enabled, two additional pieces of information must be provided to the installer: haproxy.pem and haproxy-ca-crt. These must be placed in the ~/installer-xxxx/openstack-configs directory.

haproxy.pem is the server side certificate file in PEM format. It must include the server certificate, any intermediate certificates, and the private key for the server. The common name of the certificate must match the external_lb_vip_address and/or the external_lb_vip_fqdn as configured in the setup_data.yaml file. haproxy-ca.crt is the certificate of the trusted certificate authority that signed the server side.

For production clouds, these certificates should be provided by a trusted third party CA according to your company IT policy. For test or evaluation clouds, self-signed certificates can be used quickly enable TLS. For convenience, the installer includes a script that will create and install self-signed certificates

Note	Do not use the certificates generated by this tool for production. They are for test purposes only.

To use this tool, make the following changes to the setup data file, then run the tool:

external_lb_vip_address: <IP address on external network>
external_lb_vip_tls: True
external_lb_vip_fqdn: host or DNS name matching external_lb_vip_address (if FQDN is needed)
external_lb_vip_ipv6_address: 2001:c5c0:1234:5678:1003::10   <== optional, enable IPv6 for OpenStack public endpoint

To run the tool, from the /working_dir/ directory, execute ./tools/tls_cert_gen.sh -f openstack-configs/setup_data.yaml.

OpenStack Glance Configuration with Dedicated Ceph

For OpenStack Glance, the OpenStack image service, the dedicated Ceph object storage configuration is show below. Do not change it. The Ceph and Glance keys are generated during the Ceph installation step, so you do not need to specify the keys in the setup_data.yaml file.

STORE_BACKEND: ceph #supported as ‘ceph’ for ceph backend store; don’t change

OpenStack Cinder Configuration with Dedicated Ceph

For OpenStack Cinder, the OpenStack storage service, the dedicated Ceph object storage configuration is show below. Do not change it. The Ceph and Cinder keys are generated during the Ceph installation step, so you do not need to specify the keys in setup_data.yaml file. Use the vgs command to check your volume groups available on your controller nodes. The controller nodes run the Cinder volume containers and hold the volume groups for use by Cinder. If you have available disks and want to create a new volume group for Cinder use the vgcreate command.

VOLUME_DRIVER: ceph

OpenStack Nova Configuration

To reduce the boot time, the NOVA_BOOT_FROM parameter is set to local for Cisco VIM in the OpenStack Newton release. While this reduces the boot time, it does not provide Ceph back end redundancy. To overwrite it, you can set NOVA_BOOT_FROM to ceph.

# Nova boot from CEPH
NOVA_BOOT_FROM: <ceph> #optional

OpenStack Neutron Configuration

OpenStack Neutron configuration is shown below.

# ML2 Conf – choose from either option 1 or option 2
# option 1: LinuxBridge-VXLAN
MECHANISM_DRIVERS: linuxbridge
TENANT_NETWORK_TYPES: "VXLAN"
Or
## option 2: OVS VLAN
MECHANISM_DRIVERS: openvswitch
TENANT_NETWORK_TYPES: "VLAN"
# VLAN ranges can be one continuous range or comma separated discontinuous ranges
TENANT_VLAN_RANGES: 3001:3100,3350:3400
# Jumbo MTU functionality. Only in B series, OVS-VLAN
# more info here [Mercury] Jumbo MTU feature in Mercury (B Series)
# ENABLE_JUMBO_FRAMES: True

# for Provider networks, just specifying the provider in the segments under
# the NETWORKING section is enough.
# Note : use phys_prov as physical_network name when creating a provider network

Note	When creating an external or provider network, use physical_network=phys_ext (need to be specified) or physical_network=phys_prov (need to be specified), respectively.

The JUMBO_MTU functionality is available only for OVS over VLAN in a UCS B-Series pod. In a VLAN setup, by default the MTU size is set to 1500 (1450 for VXLAN) and 8972 bytes. When JUMBO_MTU is enabled (with 28 bytes left for the header), the VLAN MTU will be 9000 and VXLAN will be 8950.

Cisco VIM also supports the installation of a handful of optional services, namely, Keystone v3 and Heat. OpenStack Heat is an orchestration service that allows you to spin up multiple instances, logical networks, and other cloud services in an automated fashion. To enable Heat, add the following Optional Services section in the setup_data.yaml file:

# Optional Services:
OPTIONAL_SERVICE_LIST:
- heat

To disable Heat, remove the Optional Services section from the setup_data.yaml file. The Optional Services support provides an infrastructure to support additional services in the future.

Note	Auto-scaling is not supported in Cisco VIM, release 2.2.

To enhance the security portfolio and multi-tenancy with the use of domains, the Keystone v3 support is added in Cisco VIM release 2.2 from an authentication end-point. Keystone v2 and Keystone v3 are mutually exclusive; an administrator has to decide the authentication end-point during installation. By default, the VIM orchestrator picks keystone v2 as the authentication end-point.

To enable Keystone v3, add the following line under the optional services section.

# Optional Services:
OPTIONAL_SERVICE_LIST:
- keystonev3

LDAP/AD support with Keystone v3

With the introduction of Keystone v3, the OpenStack service authentication can now be delegated to an external LDAP/AD server. In Cisco VIM 2.2, this feature has been introduced optionally if the authorization is done by Keystone v3.

The pre-requisite for enabling LDAP/AD integration is that the LDAP/AD endpoint should be reachable from all the Controller nodes that run OpenStack Keystone Identity Service.

To avail the LDAP/AD support with Keystone v3 feature, add the following section to the setup_data during the installation of the pod:

LDAP:
    domain: <Domain specific name>
    user_objectclass: <objectClass for Users> # e.g organizationalPerson
    group_objectclass: <objectClass for Groups> # e.g. groupOfNames
    user_tree_dn: '<DN tree for Users>' # e.g. 'ou=Users,dc=cisco,dc=com'
    group_tree_dn: '<DN tree for Groups>' # e.g. 'ou=Groups,dc=cisco,dc=com'
    suffix: '<suffix for DN>' # e.g. 'dc=cisco,dc=com'
    url: '<ldaps|ldap>://<fqdn|ip-address>:[port]'
            e.g. 'ldap://172.26.233.104:389'
            e.g. 'ldap://172.26.233.104'
            e.g. 'ldaps://172.26.233.104'
            e.g. 'ldaps://172.26.233.104:636'
            e.g. 'ldap://fqdn:389'
            e.g. 'ldap://fqdn'
            e.g. 'ldaps://fqdn'
            e.g. 'ldaps://fqdn:636'
         '<ldaps|ldap>://[<ip6-address>]:[port]'
            e.g. ldap://[2001:420:293:2487:d1ca:67dc:94b1:7e6c]:389 ---> note the mandatory "[.. ]" around the ipv6 address

    user: '<DN of bind user>' # e.g. 'dc=admin,dc=cisco,dc=com'
    password: <password> # e.g. password of bind user
    user_filter = (memberOf=CN=os-users,OU=OS-Groups,DC=mercury,DC=local)
    user_id_attribute = sAMAccountName
    user_name_attribute = sAMAccountName
    user_mail_attribute = mail             # Optional
    group_tree_dn = ou=OS-Groups,dc=mercury,dc=local
    group_name_attribute = sAMAccountName

Note	The parameter values differ based on the Directory Service provider. For Example, OpenLDAP or Microsoft Active Directory.

Integrating identity with LDAP/AD over TLS: The automation supports keystone integration with LDAP over TLS. In order to enable TLS, the CA root certificate must be presented as part of the /root/openstack-configs/haproxy-ca.crt file. The url parameter within the LDAP stanza must be set to ldaps.

The url parameter supports the following format:

url:  '<ldaps | ldap>://<FQDN | IP-Address>:[port]’

The protocol can be one of the following: ldap for non-ssl and ldaps when TLS has to be enabled.

The ldap host can be a fully-qualified domain name (FQDN) or an IPv4 or v6 address depending on how the SSL certificates are generated.

The port number is optional. If the port number is not provided, the ldap services are assumed to be running on the default ports. For example, 389 for non-ssl and 636 for ssl. However, if these ports are not the default ports, then the non-standard port numbers must be provided.

OpenStack Object Storage integration with Cisco VIM

Cisco VIM supports automated integration with a customer-managed object storage solution. The integration points reside primarily in the OpenStack Identity (Keystone) component of Cisco VIM. In the Cisco VIM 2.2, this integration is restricted to Keystone v2 only. It currently integrates with SwiftStack as the choice of object storage solution. The deployment assumes a customer-managed SwiftStack solution. Installation of the SwiftStack Controller/PACO cluster is out of scope of this document and customer should reach out to the SwiftStack team for license and installation details. While OpenStack can support multiple endpoints for a given object-store service, the current setup in the context of automation supports a single Keystone object-store service per SwiftStack PACO cluster endpoint.

The current automation uses the admin role for authentication and authorization of SwiftStack users between the Keystone SwiftStack tenant and SwiftStack account.

Pre-requisites

For a customer-managed deployment model, the minimum pre-requisites are:

• You must have a SwiftStack controller, Cluster deployed with appropriate PAC (Proxy/Account/Container) and Object configured ahead of time.
• You must know the Swift endpoint of the PAC outward facing IP address, the corresponding admin user, password and service tenant information at the time of configuring Keystone integration.
• The networking should be configured in such a way that the PAC outward facing IP address and the pod API network can talk to each other.The Keystone Auth and Keystone Auth Token middleware must be pre-configured in SwiftStack (see Keystone Configuration Requirements in SwiftStack)

The OpenStack controllers must have network reachability to the SwiftStack API endpoints, so that the Horizon and Cinder Backup service can talk to the SwiftStack endpoints.

Keystone Configuration Requirements in SwiftStack

To configure Keystone authorization, from the SwiftStack controller, choose the Cluster > Manage > Middleware > Keystone Auth option.

Note	The reseller_prefix setting enables the Keystone Auth middleware invocation at the time of authentication.

Figure 2. Configuring Keystone

To configure Keystone Auth Token Support, from the SwiftStack controller, choose the Cluster > Manage > Middleware > Keystone Auth Token Support option.

Note	auth_uri is deprecated.

# update NOVA_RAM_ALLOCATION_RATIO value in openstack_config.yaml 

Once the NOVA_RAM_ALLOCATION_RATIO is done continue with the rest of the steps as planned for installation

Cisco VIM can be deployed on the setup in one of the following install modes:

1. Connected-In this mode, the setup must be connected to Internet to fetch artifacts and docker images.
2. Dis-connected: In this mode, Cisco VIM is not connected to Internet. The artifacts and docker images are loaded from USB device.

# Install Mode: connected/disconnected
INSTALL_MODE: connected

The Cisco VIM solution uses Cisco NFVI Monitor (NFVIMON) to monitor the health and performance of the NFVI. This includes monitoring both the physical and logical components of one or multiple NFVI pods. The NFVIMON feature enables extensive monitoring and collection of performance data for various components of the cloud infrastructure including Cisco UCS blade and rack servers, service profiles, Nexus top of rack switches, fabric connections, and also the OpenStack instances. The monitoring system is designed such that it can monitor single or multiple pods from a single management system. NFVIMON is enabled by extending the setup_data.yaml file with relevant information. Also, NFVIMON can be enabled on an existing pod, through the reconfigure option. Then, the pod is added as a VIM resource to be monitored in a Control Center.

NFVIMON consists of four components: dispatcher, collector, resource manager (RM), and control-center with Cisco Zenpacks (CZ). Integration of NFVIMON into VIM is loosely coupled and the VIM automation only deals with installing the minimal software piece (dispatcher) needed to monitor the pod. The installing of the other NFVIMON components (collector, resource manager (RM) and control-center with Cisco Zenpacks (CZ), are outside the scope of the current install guide.

Before you Begin

Ensure that you have engaged with the account team for services engagement on the planning and installation of the NFVIMON accessories along with its network requirements. The image information of collector, Resource Manager (RM) and control-center with Cisco Zenpacks (CZ) is available only through Cisco Advance Services. At a high level, have a node designated to host a pair of collector VM for each pod, and a common node to host CC and RM VMs, which can aggregate and display monitoring information from multiple pods.

In terms of networking, the collectors VMs need to have two interfaces: an interface in br_mgmt of the VIM, and another interface that is routable, which can reach the VIM Installer REST API and the RM VMs. As the collector VM is in an independent node, four IPs from the management network of the pod should be pre-planned and reserved. Install steps of the collector, resource manager (RM) and control-center with Cisco Zenpacks (CZ) are Cisco advance services activities.

Cisco VIM supports the backup and recovery of the management node. By default, the feature is enabled. Auto-snapshots of the management node happens during pod management operation. You can disable the autobackup of the management node.

To enable or disable the management node, update the setup_data.yaml file as follows:

# AutoBackup Configuration
# Default is True
#autobackup: <True or False>

Some of the VNF managers operates, using specific OpenStack features that require the admin role within a given project. Cisco VIM 2.2 introduces a feature to enable non-admin role for VNF managers (such as Cisco ESC). VNF manager is used to operate and manage tenant VMs in the OpenStack cloud, with minimally enhanced privileges.

To enable this option, the administrator needs to add the following line the setup_data.yaml:

ENABLE_ESC_PRIV: True # optional; default is false

Cisco VIM supports backup and recovery of the management node, to keep the process predictable and avoid loss of logs. The software supports the capability of forwarding the ELK logs to an external syslog server.

Before launching the installation, update the setup_data.yaml file with the following information:

###################################
## SYSLOG EXPORT SETTINGS
################################### SYSLOG_EXPORT_SETTINGS:
remote_host: <Syslog_ipv4_or_v6_addr>	# required 
protocol  : udp	# defaults to udp 
facility  : <string> # required; possible values local[0-7]or user
severity  : <string; suggested value: debug>
port      : <int>; # defaults, to 514 
clients   : 'ELK'	# defaults to ELK; 
# Please note other than the remote host info, most of the other info is not needed; Also the client list is restricted to ELK only

With this configuration, the ELK logs are exported to an external syslog server. You can add this configuration to a pod that is already up and running. For more details, refer to Forwarding ELK logs to External Syslog Server section in the admin guide.
